A retainer capable of absorbing a positional difference between the moving and placing coordinates set in a moving and placing machine and the axis of a work, thus restraining the work from being defectively moved and placed. The retainer includes: a pillar-like member having a base end portion to stand on a base plate; a narrow portion formed at the center part of the pillar-like member; and a holding portion which is formed at the tip end of the pillar-like member, which is thicker than the narrow portion, and which is arranged to fit the cylindrical inner peripheral surface of a work.

Each of plural workpiece transfer units 10 input from on end of a machining line 100 in turn is fed toward the other end thereof in a first horizontal direction by a linear motor. In this transfer process, the workpiece transfer unit 100 is indexed to the front of predetermined some of plural spindle heads 60 arranged along the machining line 100, in turn. At an indexed position of the workpiece transfer unit 10, a workpiece supporting device movably mounted on the workpiece transfer unit 10 in two direction mutually perpendicular to the first horizontal direction, performs the machining operation on a workpiece in accordance with an NC program with respect to a tool T attached to a tool spindle 66 of the spindle head 60. At generally the same time when the workpiece transfer unit 10 starts a transfer feed toward the next spindle head 60 after finishing the machining operation by one of the spindle heads 60, the tool spindle 66 of the next spindle head 60 is started to rotate.

An apparatus for detecting a pallet full load state determines a pallet full load state while switching the upper limit value of the mounting height of workpieces according to workpiece size. The cell controller of an apparatus for controlling a sheet metal machining line estimates an occurrence or non-occurrence of a pallet full load state defined as a function of the overall height or the total weight of the workpieces loaded on the carrier pallet by analyzing the machining schedule when a machined workpiece is loaded on the carrier pallet and has a replacing carrier pallet good for the next workpiece to be loaded stand-by whenever appropriate. A workpiece identifying apparatus determines the XY dimensions of a batch of workpieces on a pallet by arranging a number of absolute reference points arranged on the pallet and a number of relative reference points arranged on the workpieces and calculating the differentials between the absolute reference points and the corresponding relative reference points and the XY dimensions of a square defined on the pallet. The workpiece identifying apparatus additionally determines the material of the workpieces from the surface images of the workpieces taken by the cameras it carries by sequentially referring to the surface image data stored in a surface image data storage master. The workpiece identifying apparatus further determines the thickness of each of the workpieces and the number of workpieces on the pallet by determining the height of the accumulated workpieces and the gaps between any adjacently arranged workpieces.

The present invention relates to a carrier apparatus for clamping a work by a two-dimensional rectangular motion of a pair of feed bars to automatically carry the work linearly. The carrier apparatus has at least three cams for feed and clamp rotated by an input shaft. Each of the rotational motions of these cams is transmitted to a pair of bars in parallel through the paired turrets and paired motion conversion mechanisms in the form of rectangular motions. These rectangular motions in the both feed bars are applied to the clamping motion and the feed motion for carrying the work.

An apparatus for detecting a pallet full load state determines a pallet full load state while switching the upper limit value of the mounting height of workpieces according to workpiece size. The controller of an apparatus for controlling a sheet metal machining line estimates an occurrence or non-occurance of a pallet full load state. A pallet full load state is defined as a function of the overall height or the total weight of the workpieces loaded on the carrier pallet. The controller estimates an occurance or non-occurance of a pallet full load state by analyzing the machining schedule when a machined workpiece is loaded on the carrier pallet has a replacing carrier pallet suitable for the next workpiece to be loaded standby whenever appropriate.

An automatic parts feeding system specifically adapted to feed parts having a step difference in shape over any one direction or any one side includes a loading device for receiving parts of this shape. The loading device is located above a base plate having a hole for feeding the parts to a conveyor. A part taking out device located between the loading device and the base plate transfers parts from a bottom of the loading device to the throwing hole, the part taking out device being driven such that it slidably reciprocates between the bottom of the loading device and the throwing hole.

In an assembly line system, a self-propelled carrier 51 carrying thereon assembly workpieces is brought to a halt at an assembly station 11. When the assembly of the assembly workpieces is completed at the assembly station 11, the carrier 51 is driven out therefrom. More specifically, three pairs of assembly stations 11 are disposed in serial alignment and each assembly worker A-c is placed between his/her assembly station pair. Arranged on one side of the row of these three assembly station pairs is a guide line 2d. Station guide lines 12 respectively branch off from the guide line 2d so as to establish connections between the guide line 2d and the individual assembly stations 11. A carrier orientation reversing station 15 is connected to the guide line 2d located upstream of the upstreammost assembly station 11 so that carriers 51 enter ones of the assembly station pairs, in the reverse-orientation state. Such arrangements allow the assembly workers A-C to perform assembly work on assembly workpieces for FAS products according to their respective assembly rates in an assembly line 1.

This device includes a machine tool for cutting and breaking out parts such as a glass template, a positioning shuttle for moving the glass from the cutting station to the different grinders, and multiple grinders for grinding the edgework of the glass. The system uses standard cutting, break out, and grinder machine tools. The special part of the system is the shuttle that transfers the parts to the grinders without relocation. The shuttle maintains the fixed position of the blank with regard to the X, Y axis of the cutting station through the grinding operation.
摘要:
In a pallet transfer apparatus, a base is reciprocably supported in a frame so that a hydraulic cylinder provided in the frame can drive the base. A pair of large-diameter sprockets and a pair of small-diameter sprockets are disposed on the upper and lower sides, respectively, of the frame, with a first and second endless roller chains fitted over the pairs of sprockets. The first endless roller chain includes a securing member which fixes the chain to the frame. The second endless roller chain has engaging member projected upward therefrom. In addition, a slider having a block in the intermediate part thereof is slidably mounted on a rail above the base. The engaging member engages the block. Moreover, the slider is provided with a catch for disconnectably engaging a hook of pallet P. When the base is driven by the hydraulic cylinder, the front small-diameter sprocket and the front large-diameter sprocket are integrally rotated since the first endless roller chain is fixed to the frame. As the large-diameter sprocket is rotated, the second endless roller chain is rotated, the engaging member is reciprocably moved twice the stroke of the hydraulic cylinder between the outermost points of the circumferences of the large-diameter sprockets, thus transferring pallet P by means of the slider.
